The outspoken president reiterated Montpellier's faith in the striker, although he gave the teen a few words of adviceLouis Nicollin has assured M'Baye Niang of his place at Montpellier after the striker was detained by police following a car accident last Sunday.
The 19-year-old's Ferrari was found crashed into a tree, although he denied that he was at the wheel when summoned over the incident.
Niang has reportedly had his driver's license suspended and faces jail time if found guilty, but Nicollin hopes the attacker can continue to feature prominently for Rolland Courbis' men.
"I don't excuse what he did, but we will not punish him ourselves. The important thing is that he will still score us goals," the president told reporters.
"But I have told him that if he continues like that at 19 years old, he will not always find someone [to fall back on]."
The France Under-21 international moved to Ligue 1 on loan from AC Milan in January, and has since scored three goals in four appearances.
His time in Italy was not without controversy either, where he was stopped by police for driving without a license in 2012.
